Our Planet Doesn't Seem To Be The

In Our Work, We Are Always Between Scylla And Charybdis; We May Fail To Abstract Enough, And Miss Important Physics, Or We May Abstract Too Much And End Up With Fictitious Objects In Our Models Turning Into Real Monsters That Devour Us.

What Is Especially Striking And Remarkable Is That In Fundamental Physics, A Beautiful Or Elegant Theory Is More Likely To Be Right Than A Theory That Is Inelegant. A Theory Appears To Be Beautiful Or Elegant (or Simple, If You Prefer) When It Can Be Expressed Concisely In Terms Of Mathematics We Already Have. Symmetry Exhibits The Simplicity. The Foundamental Law Is Such That The Different Skins Of The Onion Resemble One Another And Therefore The Math For One Skin Allows You To Express Beautifully And Simply The Phenomenon Of The Next Skin.

I Thought Of Killing Myself But Soon Decided That I Could Always Try Mit And Then Kill Myself Later If It Was That Bad But That I Couldn't Commit Suicide And Then Try Mit Afterwards. The Two Operations, Suicide And Going To Mit, Don't Commute.

Enthusiasm Is Followed By Disappointment And Even Depression, And Then By Renewed Enthusiasm.

The Mathematics Clearly Called For A Set Of Underlying Elementary Objects-at That Time We Needed Three Types Of Them-elementary Objects That Could Be Combined Three At A Time In Different Ways To Make All The Heavy Particles We Knew. ... I Needed A Name For Them And Called Them Quarks, After The Taunting Cry Of The Gulls, "three Quarks For Muster Mark," From Finnegan's Wake By The Irish Writer James Joyce.
